[Possible bug] Memory lekage jumboframes on RB800 ROS5.7?

RouterOS General
1

Hi,

I tried today to increase the L2MTU and the MTU on my RB800 ROS 5.7 (current-firmware: 2.30)

/interface ethernet> print detail 
Flags: X - disabled, R - running, S - slave 
0   name="Dmz" mtu=1500 l2mtu=1600  arp=enabled 
     auto-negotiation=yes full-duplex=yes speed=100Mbps 

1 R  name="External" mtu=1500 l2mtu=1600 
     arp=enabled auto-negotiation=yes full-duplex=yes speed=100Mbps 

2    name="Internal" mtu=1500 l2mtu=1600 
     arp=enabled auto-negotiation=yes full-duplex=yes speed=100Mbps

When I maxed out the L2MTU and MTU in interface Dmz and Internal I got a sudden memory leak 0.1MB every second. I reverted back and it was gone. All memory was restored. I did it again just to verify it but this time the memory was not restored when I reverted back. :confused:

This was the config at the time of the leak.

/interface ethernet print detail 
Flags: X - disabled, R - running, S - slave 
0    name="Dmz" mtu=9000 l2mtu=9116 
     auto-negotiation=yes full-duplex=yes speed=100Mbps 

1 R  name="External" mtu=1500 l2mtu=1600
      arp=enabled auto-negotiation=yes full-duplex=yes speed=100Mbps 

2    name="Internal" mtu=9000 l2mtu=9500 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=100Mbps

I have not tried this with an unit active on the interfaces. I was planing on doing it this weekend.

Can anyone else confirm this?
